I. PVC / Polyolefin Modification Plants (58% of Total Overseas Procurement Volume)

(1) Core Pain Points: Severe Powder Agglomeration, Thermal Decomposition & Discoloration Under High-Temperature Processing, Poor Resin Compatibility Leading to Deteriorated Mechanical Properties

1.Uneven Particle Size & Hygroscopic Agglomeration Causing Surface Defects & Reduced Production Efficiency Challenges: Conventional general-grade MHC features D50 of 9~15μm and D90 ≥20μm. When stored at ambient humidity above 55% for 7 days, powder agglomeration rate reaches 35%. When applied to PVC extrusion and PP pelletizing, agglomerated particles fail to disperse fully, creating white spots and pitting ranging from 0.4mm to 3mm on finished goods, pushing surface defect rates to 28%. Agglomerates also accelerate extruder screen clogging, shortening cleaning cycles to 48 hours and tripling maintenance frequency, cutting overall line productivity by 22%. Root Cause Explanation: MHC is a polar layered inorganic powder with surface active groups readily adsorbing atmospheric moisture to induce particle adhesion and agglomeration. Broad particle size distribution paired with agglomerates disrupt uniform melt flow, manifesting as surface defects and accelerated equipment wear on finished products.

2.Low Thermal Decomposition Temperature Triggering Product Discoloration & Failed Thermal Stabilization Under High-Temperature Processing Challenges: Standard MHC initial thermal decomposition temperature ranges from 190~210°C, while mainstream PVC and polyolefin processing temperatures fall between 185~230°C. Once processing temperatures exceed 220°C, 30% of finished goods develop yellowing and browning; PVC thermal stabilization duration drops from the standard 25 minutes to only 12 minutes, failing to meet the EU minimum threshold of 20 minutes. When used as a halogen scavenger, 25% of batches exceed 80ppm residual chloride, violating overseas environmental control standards. Root Cause Explanation: MHC interlayers contain crystal water that rapidly escapes at high temperatures, destroying layered structures and eliminating thermal stabilization and halogen adsorption capacity. Decomposition byproducts catalytically accelerate PVC resin degradation, directly triggering material discoloration.

3.Weak Interfacial Bonding Causing Sharp Declines in Product Mechanical Performance Challenges: Adding 15% standard MHC to homopolymer PP reduces original tensile strength from 32MPa to 23MPa (28.1% drop) and notched impact strength from 6.5kJ/m² to 3.8kJ/m² (41.5% drop). Adding 20% MHC to flexible PVC cuts elongation at break from 220% to 110% (50% reduction). Statistically, over 40% of batches fail to meet general overseas mechanical performance standards for plastic goods. Root Cause Explanation: MHC is a highly polar inorganic powder with high interfacial tension against non-polar polyolefins and weakly polar PVC. Weak bonding between powder and resin matrices creates internal stress concentration points that disrupt material structural continuity.

(2) Targeted Solutions

1.

Ultra-Fine Particle Size + Anti-Agglomeration Surface Coating to Improve Dispersibility & Production Conditions Hard acid surface modification is applied to control powder particle size at D50=3~5μm and D90≤8μm. Post-modification, agglomeration rate is limited to below 4% after 30 days of storage at 60% relative humidity. For PVC production lines, surface defect rates fall below 2%, screen clogging cycles extend to 7 days, and overall productivity recovers by 18%.

2.Intercalation Modification + Low-Temperature Calcination Technology to Boost Thermal Stability & Broaden Processing Windows High-temperature calcination paired with silane intercalation optimizes MHC structure, lifting initial thermal decomposition temperature to 270°C. The material maintains stable performance at processing temperatures up to 230°C with no yellowing or browning; PVC thermal stabilization duration holds steady at 28 minutes, and residual chloride in finished goods ≤50ppm, fully complying with EU standards.

3.Special Silane Coupling Agent Coating to Strengthen Interfacial Compatibility & Preserve Mechanical Performance 1.2% KH-570 silane coupling agent coats powder surfaces. After adding 15% modified MHC to PP matrices, tensile strength stabilizes at 29MPa and impact strength at 5.7kJ/m², retaining over 87% of original mechanical performance. Flexible PVC elongation at break recovers to 190%, satisfying overseas general mechanical requirements for plastic products.

II. Automotive Rubber & Plastic Component Manufacturers (24% of Total Overseas Procurement Volume)

(1) Core Pain Points: Precipitation Under Hot-Humid Conditions, Excessive VOC & Smoke Density, Sharply Reduced Impact Strength in Glass Fiber-Reinforced Systems

1.

Poor Hydrolysis Resistance Triggering Post Hot-Humid Aging Precipitation That Impairs Appearance & Insulation Performance Challenges: After 500 hours of hot-humid aging at 85°C & 85% RH, standard MHC precipitation rate ≥7.5%, causing surface whitening and 40% higher haze in plastic parts. Material volume resistivity drops from an initial 10¹⁴Ω·cm to 10¹⁰Ω·cm, falling below the mandatory insulation threshold of ≥10¹²Ω·cm for new energy vehicle components. 32% of non-compliant batches are fully scrapped. Root Cause Explanation: MHC layered structures swell upon water exposure, enabling outward migration of interlayer anions to form surface precipitates. The powder’s inherent hydrophilicity accelerates moisture penetration, jointly damaging product appearance and electrical insulation performance.

2.

3.

Excessive Volatiles & Smoke Density Failing Automaker Environmental Certifications Challenges: Major European automakers follow VW 50185 interior material standards requiring TVOC ≤50μg/m³ and smoke density Ds ≤300. Standard MHC delivers TVOC of 95μg/m³ and Ds of 380, failing both metrics. 40% of supply batches are rejected by OEMs, triggering order defaults and client churn. Root Cause Explanation: Residual unreacted small organic molecules on standard MHC surfaces volatilize continuously under high-temperature operating conditions, elevating TVOC readings. Incomplete layered decomposition during combustion forms loose char layers that release excessive smoke.

4.

5.

Agglomeration with Glass Fiber & Rubber Severely Cutting Impact Strength Challenges: Adding 12% standard MHC to 30% glass fiber-reinforced PP reduces baseline impact strength from 8.5kJ/m² to 4.2kJ/m² (50.6% drop), falling below the minimum 6kJ/m² threshold for automotive structural load-bearing and shock-resistant components. Root Cause Explanation: MHC powder readily agglomerates with glass fibers, creating abundant structural defects at resin-fiber interfaces that generate severe stress concentration and drastically weaken impact resistance.

6.

(2) Targeted Solutions

1.

Polyurea Microcapsule Hydrophobic Coating to Boost Hydrolysis & Precipitation Resistance Full encapsulation with 280°C heat-resistant polyurea compounded with 0.6% hydrolysis stabilizer.

6.

III. Electronic & New Energy Material Manufacturers (12% of Total Overseas Procurement Volume)

(1) Core Pain Points: Weak Flame Retardant Synergy for Ultra-Thin Parts, High-Temperature Migration During Reflow Soldering Lowering Tracking Resistance, Excessive Heavy Metals & Impurities

1.

Insufficient Flame Retardant Synergy for Ultra-Thin Components, Low UL94 V-0 Compliance Rate Challenges: Clients produce 0.6~0.8mm battery casings and electronic connectors. Standard MHC paired with primary flame retardants only achieves a 55% UL94 V-0 pass rate, with self-extinguishing times exceeding 30 seconds and molten dripping common. Single UL certification costs $900 with a 4–5 week testing cycle; 25% of orders face delayed market launch due to prolonged certification timelines. Root Cause Explanation: Ultra-thin workpieces possess low thermal capacity. Standard MHC forms char layers slowly with loose structures that fail to rapidly block flame propagation, delivering insufficient flame retardant synergy to pass stringent thin-part fire testing.

2.

3.

Component Migration During High-Temperature Reflow Soldering Reducing Comparative Tracking Index (CTI) Challenges: Electronic components undergo SMT reflow soldering at 255~260°C. Post-processing, 22% of finished goods exhibit minor MHC migration, dropping CTI from an initial 600V to below 380V, failing the IEC 60112 minimum requirement of ≥500V. Product scrap rate reaches 16%. Root Cause Explanation: High temperatures degrade MHC surface coating layers, allowing polar active components to migrate to product surfaces and form weak conductive pathways that drastically reduce tracking resistance.

4.

5.

Excessive Heavy Metals & Free Chloride Failing RoHS & REACH Compliance Testing Challenges: Standard industrial-grade MHC contains total heavy metals ≥8ppm, exceeding the EU limit of ≤5ppm; free chloride ≥80ppm, with 30% of batches failing compliance inspections and barring market access in the EU and North America. Root Cause Explanation: Low-purity magnesium and aluminum feedstock paired with incomplete water washing processes leave residual heavy metal ions and free chloride in finished products.

6.

(2) Targeted Solutions

1.

High-Purity Nano-Grade Product + Synergistic Fillers to Stabilize UL94 V-0 Ratings for Ultra-Thin Components Supply high-purity MHC with total heavy metals ≤3ppm compounded with 4% nano-montmorillonite as a flame retardant synergist.

Optimized testing formulations cut single certification costs to $400 and reduce testing cycles to 2 weeks.

2.

3.

High-Temperature Epoxy Resin Coating to Suppress High-Temperature Component Migration 300°C heat-resistant epoxy resin coats powder surfaces with 0.8% anti-migration additives incorporated. After 260°C reflow soldering, product CTI remains stable at 600V, limiting scrap rates to below 2%.

4.

5.

6.

IV. Chemical Trading Distributors (6% of Total Overseas Procurement Volume)

(1) Core Pain Points: High Minimum Order Quantity Thresholds, Severe Price Volatility Driven by Upstream Raw Material Costs, Inconsistent Batch Quality & Insufficient Technical Support

1.

High Standard MOQ Raising Small-Batch Procurement Costs & Inventory Overstock Risks Challenges: Factory standard MOQ stands at 1 ton, while distributor downstream clients are small-to-medium modification and plastic factories with single order demands of 50~200kg. Split small-batch sourcing incurs a 17%~23% procurement premium; bulk stocking creates capital-intensive inventory backlogs, driving 38% of downstream end-users to switch to competing products over cost concerns.

2.

3.

Upstream Raw Material Price Hikes Translating to Wild MHC Price Fluctuations & Shrinking Profit Margins Challenges: MHC FOB prices range from $12.5~14.5/kg, with quarterly price swings up to ±10% driven by magnesium oxide and aluminum oxide feedstock costs. Overseas distributors maintain gross margins of only 3%~5%, risking purchase-selling price inversion during sharp volatility and severe operational risks.

4.

5.

Inconsistent Batch Indicators & Delayed Technical Support Causing High Client Complaint Rates Challenges: Conventional products display particle size deviations of ±3μm and thermal decomposition temperature deviations of ±20°C across batches, triggering unstable performance for end-users. When clients encounter poor powder dispersion, precipitation and performance inconsistencies, technical response times exceed 72 hours, pushing overall customer complaint rates to 28% and eroding repeat purchase rates.

6.

(2) Targeted Solutions

1.

Split Independent Small Packaging with Flexible Tiered MOQs 25kg independent bag packaging is launched, lowering the minimum order quantity to 250kg. For scattered 50~200kg orders, repackaging premiums are capped at 5%.

2.

3.

Long-Term Price Lock Agreements + Tiered Volume Discounts to Hedge Price Risks 12-month fixed supply contracts lock base unit prices at $13.2/kg. Quarterly cumulative purchases ≥25 tons qualify for an additional 3% volume discount. Price fluctuations are controlled within ±2.5% throughout the contract term, lifting distributor stable gross margins to 6%~7%.

I. Procurement Mindset & Core Focus Indicators for Global B2B Buyers

Based on mainstream global procurement models and downstream application scenarios, we categorize buyers into six major groups: purchasers of high-end PVC/medical-grade products, wire & cable compound buyers, general rubber & plastic product purchasers, engineering modified plastic buyers, fire-resistant building material/outdoor product buyers, and cross-border chemical distribution buyers. Each group is elaborated below by regional distribution, pre-procurement evaluations, production adaptability requirements, and key quality inspection indicators.

(1) High-End PVC / Medical-Grade Product Buyers: Prioritize Safety Compliance, Thermal Stability & Low Migration

Concentrated in regions with mature regulatory frameworks including Western Europe, North America, Japan, South Korea, Australia and New Zealand, these buyers manufacture premium rigid/flexible PVC goods, medical plastic components, food-contact pipes, sealing strips, high-transparency PVC profiles, and infant plastic accessories. Their products come into direct contact with human bodies, food or medical environments, making safety compliance the top procurement priority, alongside stringent requirements for product appearance and long-term service stability.

1. Pre-Procurement Comprehensive Considerations First, fully verify global special safety and environmental certifications. Beyond general environmental directives such as REACH and RoHS, food-contact products must comply with EU Regulation EU 10/2011 and US FDA standards; medical products need to meet ISO 10993 biocompatibility requirements. Buyers also audit heavy metal and toxic ion content to confirm no harmful modifying additives are incorporated. HiSiaddi provides multi-lingual MSDS, third-party test reports and full-batch traceability documents to support import filing and random inspection requirements worldwide.

Second, test formula compatibility and long-term service performance. MHC serves as the primary thermal stabilizer, so buyers conduct long-term aging tests to verify its capacity to absorb hydrogen chloride released during PVC processing and service, assessing long-duration thermal stabilization efficiency. For transparent and light-colored products, tests are performed to check for yellowing, increased haze, surface precipitation and blooming induced by additives. For medical goods, additional tests for disinfection resistance and body fluid compatibility are carried out to eliminate safety risks from additive migration.

Third, evaluate supply chain stability and dust-free delivery capacity. Most clients sign annual framework long-term orders with highly automated production lines demanding strict consistency across batches. Buyers audit suppliers’ modification processes, dust-free workshops and quality control protocols, preferring partners with stable production capacity, fixed batch delivery and fully clean packaging.

In terms of pricing, these buyers accept reasonable premiums and never compromise on quality to cut costs, with safety and performance always taking precedence.

1. Core Product Indicators for Procurement (Stringent Standards with Precise Parameter Control)

2. Modification Coating Effect: Surface modification is the core attribute of MHC. Incomplete coating leads to powder agglomeration and poor compatibility with PVC, directly impairing stabilization performance and product appearance – this is the primary inspection indicator.

3. Thermal Stabilization Efficiency & Acid Absorption Capacity: Dynamic and static thermal aging duration and hydrogen chloride absorption capacity are tested to determine PVC’s resistance to decomposition during processing and long-term use.

4. Heavy Metals & Soluble Ions: Strict limits on lead, cadmium, mercury, arsenic and other heavy metals, as well as chloride and alkali metal ions, mitigate safety hazards for food and medical applications.

5. Particle Size & Particle Size Distribution: Fine, uniformly distributed powder ensures high transparency and low haze, a critical requirement for light/transparent finished products.

6. Moisture Content: Excessive moisture causes internal bubbles and surface defects in products while accelerating powder agglomeration, with control thresholds far stricter than general industrial grades.

7. Precipitation Rate & Migration Resistance: Prevent additive migration from substrates to guarantee safety and intact appearance for contact-use products.

8. Initial Whiteness & Yellowing Resistance: Control raw material base color and test yellowing rates under prolonged heat and light exposure to maintain consistent product aesthetics.

(2) Wire & Cable Compound Buyers: Focus on Temperature Resistance, Insulation & Long-Term Stability

Distributed across global industrial hubs including Europe, Southeast Asia, the Middle East and South America, these buyers produce high/low voltage cable sheaths, insulation layers, cable auxiliary materials, photovoltaic cables and locomotive wiring. Cables operate under continuous electrification and are buried or installed outdoors long-term, requiring outstanding electrical insulation, temperature resistance, weatherability and flame retardant synergistic effects. MHC functions here as a thermal stabilizer, flame retardant synergist and acid scavenger.

1. Pre-Procurement Comprehensive Considerations First, confirm industry compliance and electrical material standards. Beyond general environmental regulations, products must align with regional cable industry standards. High-voltage and new energy cables additionally require additives that do not degrade insulation resistance or voltage resistance. Buyers verify safety under prolonged electrification and high temperatures to avoid electric leakage and accelerated aging.

Second, validate adaptability to high-temperature processing and long-term operating conditions. Cable extrusion operates at elevated temperatures with extended processing cycles; buyers test MHC stability under sustained high heat to check for decomposition and performance failure. For outdoor and underground cables, temperature cycling and high-humidity simulations evaluate performance attenuation over decades of service, alongside synergistic compatibility with cable-specific plasticizers, flame retardants and antioxidants.

Third, prioritize powder flowability and feeding compatibility. Highly automated cable production lines rely on automatic feeding systems, requiring MHC to resist moisture absorption and caking with excellent flowability to ensure uninterrupted continuous mass production.

Long/medium-term orders are preferred, with consistent batch parameters to prevent performance fluctuations in finished cables; logistics packaging features robust moisture and dust protection.

1. Core Product Indicators for Procurement (Centered on Electrical Performance & Temperature Resistance)

2. Thermal Decomposition Temperature: Ensure no decomposition under cable processing and continuous operating temperatures to sustain acid absorption and thermal stabilization functions.

3. Electrical Insulation Indicators: Test volume resistivity and dielectric properties to confirm MHC does not downgrade cable insulation grades – a unique core indicator for the cable sector.

4. Moisture & Moisture Absorption Rate: Moisture compromises both processing and insulation performance, mandating strict moisture limits and strong anti-hygroscopic properties.

5. Particle Size & Dispersibility: Uniform dispersion guarantees consistent cable performance, as localized defects create severe safety risks.

6. Flame Retardant Synergistic Performance: Deliver effective smoke suppression and flame retardancy when paired with primary flame retardants to elevate cable fire safety ratings.

7. Free Alkali Content: Excess free alkali corrodes cable substrates and destabilizes formula systems, requiring tight concentration limits.

(3) General Rubber & Plastic Product Buyers: Prioritize Cost-Performance for Basic Application & Mass Production

This group represents the largest global procurement volume, concentrated in emerging markets including Southeast Asia, Eastern Europe, the Middle East, Africa and South America. They manufacture standard PVC pipes, civilian plastic hoses, ordinary sealing strips, artificial leather and daily plastic parts. Low industry entry barriers, fierce market competition and thin profit margins define their core procurement logic: "adequate performance at low cost with flexible supply".

1. Pre-Procurement Comprehensive Considerations First, comprehensive procurement cost is the decisive factor. Buyers compare unit prices, international freight, tariffs and warehousing to select suppliers with the lowest end-to-end costs. Commercial terms including minimum order quantity (MOQ), payment terms, credit periods and replenishment speed are heavily negotiated, with preference for small-batch, multi-batch cooperation models.

Second, basic formula compatibility is sufficient. MHC only needs to mix normally with standard PVC and common additives to fit simple extrusion and calendering processes; complex aging and migration specialized tests are not conducted, with no high-end performance requirements.

Third, fast supply response is a high priority. Frequent fluctuating orders for civilian goods create urgent restocking demands, requiring suppliers with ample inventory and mature logistics routes to deliver quickly without halting production lines.

Fourth, compliance only meets basic import requirements of destination countries. Only customs clearance documents including MSDS, quality inspection certificates and certificates of origin are required to satisfy general chemical import thresholds, with no special certifications for food, medical or cable applications.

1. Core Product Indicators for Procurement (General Industry Standards with Acceptable Parameter Fluctuations)

2. Basic Thermal Stabilization Performance: Meets anti-aging requirements for standard processing and short-term service of civilian products, with no demand for long-duration, high-precision thermal stabilization.

3. Moisture & Anti-Caking Properties: Only severe caking that disrupts mixing and feeding is rejected.

4. Standard Particle Size: No strict controls over particle size distribution or fineness; absence of large particles causing obvious product defects suffices.

5. Free Alkali & pH Value: Maintained within general industry ranges to avoid formula abnormalities.

6. Basic Whiteness: Irrelevant for dark products; light-colored goods only require freedom from obvious discoloration.

(4) Engineering Modified Plastic Buyers: Balance Filling Reinforcement, Processing Flowability & System Compatibility

Distributed across major global industrial manufacturing hubs, these buyers produce polyolefin modified compounds, glass fiber-reinforced plastics, injection-molded structural components and general industrial modified materials. MHC acts as a functional filler, thermal stabilizer and flame retardant synergist, delivering balanced mechanical performance, processability and auxiliary functionality via twin-screw extrusion and high-temperature modification.

1. Pre-Procurement Comprehensive Considerations First, test compatibility with resins, glass fiber and diverse additives. Modified plastic formulas are complex, frequently incorporating glass fiber, tougheners, antioxidants and flame retardants. Buyers conduct repeated mixing trials to eliminate agglomeration, delamination and functional failure of MHC, while evaluating impacts on tensile, impact and flexural mechanical properties – balancing auxiliary functionality with retention of base material strength.

Second, assess processing flowability. High-filling systems demand excellent powder flowability; MHC surface modification directly impacts mixing and extrusion efficiency, requiring easy dispersion, no equipment adhesion and compatibility with automated modification lines.

Third, evaluate temperature resistance range. Engineering plastics operate across broad processing temperature windows, requiring additives to maintain stable performance without decomposition or volatilization under wide temperature fluctuations.

Orders are medium-volume periodic batches with strict batch consistency mandates to guarantee uniform finished modified compound performance. Compliance aligns with environmental or industry standards as required by end-product applications.

1. Core Product Indicators for Procurement (Focused on Reinforcement, Flow & Dispersion Parameters)

2. Oil Absorption Value: A core metric for modified fillers. Excessively high oil absorption adsorbs large volumes of plasticizers and additives in formulas, raising production costs and impairing product performance – requiring rigorous control.

3. Powder Flowability & Dispersibility: Ensure smooth high-mixing and extrusion with uniform powder distribution within resin matrices.

4. Bulk Density: Match metering batching systems to guarantee precise formula ratios.

5. Thermal Stability: Adapt to high-temperature modification processes to prevent additive thermal decomposition.

6. Impurity Content: Stringently limit mechanical impurities and large particles to avoid equipment damage and product defects.

Concentrated in infrastructure-developed regions including Europe, Australia, Southeast Asia, tropical Middle Eastern territories and South America, these buyers manufacture fire-resistant construction boards, outdoor PVC profiles, roofing waterproof accessories, outdoor guardrails and landscape plastic products. Constant exposure to UV radiation, rainfall and temperature swings alongside mandatory construction fire safety standards creates dual requirements for flame retardancy and weatherability.

1. Pre-Procurement Comprehensive Considerations First, verify local specialized standards for construction fire resistance and outdoor materials. National regulations mandate specific flame retardant ratings, smoke output limits and weatherability lifespans for building materials. Buyers validate MHC’s capacity as a flame retardant synergist and stabilizer to help end products pass regional construction material testing.

Second, conduct extensive long-term weathering testing for outdoor service. Simulate UV irradiation, temperature alternation and rain erosion to evaluate long-term additive failure, precipitation and pulverization, determining product service life. Smoke suppression capacity is a core safety requirement for fire scenarios in buildings.

Third, assess large-volume supply capacity. Construction projects generate bulk concentrated orders, requiring suppliers with sufficient production capacity to deliver full containers aligned with project timelines.

Formulas are optimized for outdoor-grade PVC and thermal insulation filling systems to preserve structural and performance integrity over decades of service.

1. Core Product Indicators for Procurement (Highlighting Weather Resistance, Smoke Suppression & Long-Term Stability)

These buyers are wholesale chemical traders at major global chemical ports and regional distribution hubs, with no in-house manufacturing. They purchase MHC in full-container loads for repackaging, regional transit and resale to local small-to-medium factories. Their core procurement demands are easy transportation, stable warehousing, smooth customs clearance, universal applicability and minimal material loss.

1. Pre-Procurement Comprehensive Considerations First, demand universal, complete certification documentation. Goods are resold across multiple countries and downstream sectors, requiring multi-lingual MSDS, general quality inspection reports, certificates of origin and universal compliance certifications. A single set of documents must support cross-border customs clearance and client audits, with niche specialized certifications rejected.

Second, thoroughly evaluate stability during long-distance ocean shipping and prolonged warehousing. As a powder raw material, MHC undergoes transoceanic transport, cross-climate transit and long-term storage. Buyers prioritize moisture absorption rate, anti-caking capacity and room-temperature shelf life, alongside packaging moisture/dust/breakage protection to prevent product deterioration and agglomeration in transit.

Third, exclusively source mainstream general specifications, rejecting custom-modified grades to ensure compatibility with all standard downstream applications and reduce inventory stagnation risks.

Fourth, meticulously calculate profit margins by integrating purchase prices, freight, repackaging loss and warehousing costs, preferring products with stable pricing and consistent supply. Bulk ton bags and small consumer packaging formats are supported to accommodate diverse client order sizes.

1. Core Product Indicators for Procurement (Circulation Metrics Prioritized, Performance Meeting General Industrial Baselines)

2. Moisture Absorption Rate & Anti-Caking Capacity: The primary circulation indicator, directly governing product usability post-storage and transit.

3. Room-Temperature Storage Stability: Consistent main component concentration, pH value and appearance throughout shelf life.

4. Moisture Content: Lower moisture minimizes risks during cross-regional shipping and long-term storage.

5. Dust Generation: Low-dust products reduce material loss and operational hazards during loading, unloading and repackaging.

6. Basic Physicochemical Indicators: Modification effect, thermal stability and particle size undergo routine sampling inspection only, with compliance to general industrial standards sufficient – no deep specialized testing required.
